A gap under the garage door in Sunnyvale usually means a worn bottom seal or an uneven door. Both are quick, affordable fixes.

In Sunnyvale, the weather is often part of the story behind a gap under the garage door. Months of coastal salt air and inland heat mean salt air corrodes hardware and daily use wears rollers across Santa Clara County — exactly the kind of wear a local tech knows to check first.
